[2008] Tabbed Pages Problems

[ajwak95]

I'm sorry I keep having problems. But this will prob. be one of my last for a while. I am having a problem with my tabbed browser. What I did was I put in a code like this

Private Sub ToolStripButton5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton5.Click
        webbrowser.Navigate(txturl.Text)
        WebBrowser1.Navigate(txturl.Text)
    End Sub

What I am trying to do is have Multible tab in which when you go to one webpage it stays on that tab, and is not displayed on the other tab (so you can have google on one tab and yahoo! Mail on the other). What is happening is that when I type in a url in one tab it also shows in the other tab. There are no errors showing.

thats because you're telling both webbrowser + WebBrowser1 to .Navigate(txturl.Text)

Here's what I suggest for a tabbed Web browser. You inherit the TabPage class and add a constructor that creates a WebBrowser control and adds it to the page. You would then either expose that WebBrowser control via a public property, which is easier, or else declare members in your TabPage class that in turn access the corresponding members of the WebBrowser control. Here's an example of the first option:

Public Class WebBrowserTabPage
    Inherits System.Windows.Forms.TabPage
 
    Private WithEvents _webBrowser As New WebBrowser
 
    Public ReadOnly Property WebBrowser() As WebBrowser
        Get
            Return Me._webBrowser
        End Get
    End Property
 
    Public Sub New()
        Me._webBrowser.Dock = DockStyle.Fill
        Me.Controls.Add(Me._webBrowser)
    End Sub
 
    Private Sub _webBrowser_DocumentTitleChanged(ByVal sender As Object, _
                                                 ByVal e As EventArgs) Handles _webBrowser.DocumentTitleChanged
        Me.Text = Me.WebBrowser.DocumentTitle
    End Sub
 
End Class

Now, instead of adding regular TabPages, you add instances of your WebBrowserTabPage to your TabControl. You will have to do this in code, which you'd do anyway as you opened knew pages:

Me.TabControl1.TabPages.Add(New WebBrowserTabPage)

Now it's easy to ensure you refer to only the browser on the selected tab:

DirectCast(Me.TabControl1.SelectedTab, WebBrowserTabPage).WebBrowser.Navigate("URL here")

Also, if you're using a single address bar and the like you can handle the SelectedIndexChanged event of the TabControl and get the correct address easily to display.
